Abstract
The interval between arrival of two time displaced signals is measured with a resolution less than 0.5 nanoseconds by electronic vernier techniques utilizing transferred electron logic device circuits. The first arriving signal triggers a first clock generator of pulse period T.sub.C, the pulses from which are counted by a first counter and a second counter. The second arriving signal triggers a second clock pulse generator having a pulse period T.sub.V, the first pulse therefrom disabling the first counter at a count of M. As T.sub.V <T.sub.C coincidence of the pulses from the two clock pulse generators will eventually occur causing disabling of the second counter at a count of N. Time interval .DELTA.T is computed from the formula: .DELTA.T=(N-1)T.sub.C -(N-M)T.sub.V.
